由于在目前的机动车环检检测过程中，大部分车辆只检测驱动轮而忽略了非驱动轮的检测。例如：前驱车在道路行驶时，前轮作为驱动轮是在做正功，而后轮作为非驱动轮在做负功，而检测过程中前驱车只检测前轮，这样无法完全模拟车辆在道路行驶的情况。本发明通过将非驱动轮产生的负荷加载到驱动轮上的控制方法，真实模拟了车辆在道路的情况。Because in the current environmental inspection and detection process of motor vehicles, most vehicles only detect the driving wheels and ignore the detection of non-driving wheels. For example: when a front-wheel-drive vehicle is driving on the road, the front wheel is doing positive work as the driving wheel, and the rear wheel is doing negative work as a non-driving wheel. However, the front-wheel drive vehicle only detects the front wheels during the detection process, which cannot completely simulate the vehicle driving on the road. Case. The invention truly simulates the situation of the vehicle on the road through the control method of loading the load generated by the non-driving wheels on the driving wheels.
控制方法如下：The control method is as follows:
读取前、后底盘测功机转速传感器信号，判断前、后轮转速是否一致，若一致则继续检测；若不一致，则计算此时前后轮速度差，再根据前、后轮转速大小以及检测车辆所处工况进行调节：Read the speed sensor signals of the front and rear chassis dynamometers to determine whether the front and rear wheel speeds are consistent, and if they are consistent, continue to detect; if not, calculate the speed difference between the front and rear wheels at this time, and then use Adjust the working condition of the vehicle:
若前轮转速大于后轮转速且此时为加速工况，则增加后轮转速，并且计算此时后底盘测功机电机负荷的增加量ΔP1，并且通过前底盘测功机电机给前轮额外加上ΔP1的负荷量，然后再次判断判断前、后轮转速是否一致，若不一致则重复该循环直至一致；若一致则继续检测。If the speed of the front wheels is greater than the speed of the rear wheels and it is an acceleration condition, increase the speed of the rear wheels, and calculate the increase ΔP 1 of the motor load of the rear chassis dynamometer at this time, and feed the load to the front wheels through the motor of the front chassis dynamometer. Add the additional load of ΔP 1 , and then judge again whether the speeds of the front and rear wheels are consistent. If not, repeat the cycle until they are consistent; if they are consistent, continue testing.
若前轮转速大于后轮转速且此时为减速工况，则降低前轮转速，并且计算此时前底盘测功机电机负荷的减少量ΔP2，并且通过后底盘测功机电机使后轮减少ΔP2的负荷量，然后再次判断判断前、后轮转速是否一致，若不一致则重复该循环直至一致；若一致则继续检测。If the speed of the front wheel is greater than the speed of the rear wheel and it is a deceleration condition at this time, then reduce the speed of the front wheel, and calculate the load reduction ΔP 2 of the motor load of the front chassis dynamometer at this time, and make the rear wheel Reduce the load of ΔP 2 , and then judge again to determine whether the front and rear wheel speeds are consistent. If not, repeat the cycle until they are consistent; if they are consistent, continue testing.
若后轮转速大于前轮转速且此时为加速工况，则增加前轮转速，并且计算此时前底盘测功机电机负荷的增加量ΔP3，并且通过后底盘测功机电机给后轮额外加上ΔP3的负荷量，然后再次判断判断前、后轮转速是否一致，若不一致则重复该循环直至一致；若一致则继续检测。If the speed of the rear wheels is greater than the speed of the front wheels and it is an acceleration condition, increase the speed of the front wheels, and calculate the increase ΔP 3 of the motor load of the front chassis dynamometer at this time, and feed the load to the rear wheels through the motor of the rear chassis dynamometer. Add the additional load of ΔP 3 , and then judge again to determine whether the front and rear wheel speeds are consistent, if not, repeat the cycle until they are consistent; if they are consistent, continue testing.
若后轮转速大于前轮转速且此时为减速工况，则降低后轮转速，并且计算此时后底盘测功机电机负荷的减少量ΔP4，并且通过前底盘测功机电机使前轮减少ΔP2的负荷量，然后再次判断判断前、后轮转速是否一致，若不一致则重复该循环直至一致；若一致则继续检测。If the rear wheel speed is greater than the front wheel speed and it is a deceleration condition at this time, then reduce the rear wheel speed, and calculate the load reduction ΔP 4 of the rear chassis dynamometer motor at this time, and use the front chassis dynamometer motor to make the front wheel Reduce the load of ΔP 2 , and then judge again to determine whether the front and rear wheel speeds are consistent. If not, repeat the cycle until they are consistent; if they are consistent, continue testing.
其中，车辆所处工况是由国标（GB18285—2005《点燃式发动机汽车排气污染物排放限值及测量方法（双怠速法及简易工况法）》和GB3847—2005《车用压燃式发动机和压燃式发动机汽车排气烟度排放限值及测量方法》）中规定的检测过程决定的。电控单元通过读取程序中车辆此时对应的工况。Among them, the working condition of the vehicle is determined by the national standard (GB18285-2005 "Limits and Measurement Methods of Exhaust Pollutants from Ignition Engine Vehicles (Double Idling Method and Simple Working Condition Method)" and GB3847-2005 "Compression Ignition Engine for Vehicles" Engine and compression ignition engine vehicle exhaust smoke emission limits and measurement methods ") determined by the testing process specified. The electronic control unit reads the corresponding working conditions of the vehicle in the program at this time.
具体的检测流程如下：The specific detection process is as follows:
1）当有车辆需要检测时，根据车辆的轴距将前、后底盘测功机放置好，使前、后底盘测功机的中心距离与车辆轴距相等。1) When there is a vehicle to be tested, place the front and rear chassis dynamometers according to the wheelbase of the vehicle so that the center distance between the front and rear chassis dynamometers is equal to the vehicle wheelbase.
2）启动定位装置使底盘测功机呈水平放置。2) Start the positioning device so that the chassis dynamometer is placed horizontally.
3）将车辆驶上底盘测功机并且将地锚牵引装置连接在车辆上。3) Drive the vehicle onto the chassis dynamometer and connect the ground anchor traction device to the vehicle.
